Abstract

The invention relates to a two-degree-of-freedom servo mechanism suitable for micro sonar, which belongs to the technical field of micro sonar servo and solves the problem that the existing servo mechanism is not suitable for micro sonar installation. The two-degree-of-freedom servo mechanism includes: a fixed spherical joint and a horizontal transmission part and a vertical transmission part with the same structure; the center of the bottom of the miniature sonar is connected to the installation carrier of the miniature sonar through the fixed spherical The vertical transmission part is connected to the installation carrier of the miniature sonar, and the horizontal transmission part and the vertical transmission part are arranged orthogonally; the horizontal transmission part includes a servo ball joint, a connecting rod, and a linear actuator hinged in sequence, and the servo ball joint is connected to the bottom of the miniature sonar , the linear actuator is connected with the mounting carrier of the miniature sonar. The invention has reasonable structural layout and high integration, fully utilizes the rear-end installation space of the miniature sonar, can simultaneously realize the motion of the miniature sonar in two directions of pitch and yaw, and has high reliability.

Description

technical field [0001] The invention relates to the technical field of miniature sonar servo, in particular to a two-degree-of-freedom servo mechanism suitable for miniature sonar. Background technique [0002] Sonar is an electronic device that uses the characteristics of sound waves to propagate underwater, through sound-to-electric conversion, to realize functions such as underwater detection and underwater communication. It is the most commonly used navigation and positioning technology for underwater vehicles and underwater robots. Sonar emits some form of acoustic signal, which is detected by the echo reflected by obstacles or targets on the way of signal propagation in water. [0003] The traditional installation method of sonar is fixedly installed at the front end of the underwater vehicle or underwater robot. There are limitations in emitting sound waves and receiving echoes, which seriously restricts the effective detection area of ​​sonar. The frontmost position...
